Re: Mitsi VRF not cooling
If you suspect you have damaged the valve when you replaced it this could be the issue. If the valve is stuck open the best way to check would be to turn that indoor unit off while you run A couple of units on the system and feel the suction line... if it’s cold after 5-10mins Id suspect it is passing and requires replacing. You may also be able to hear refrigerant hissing throughly the coil or even use the dip switches to check the suction pipe temp but it will be pretty obvious if it’s passing I’d have thought.
dont be to concerned about the demand of the indoors on the condenser aswel, Mitsi allow 150% diversity if required.
